GTG
Scripts are served from your own domain through a lightweight proxy, so they no longer look like Google traffic. Many ad blockers still catch on.
Automated checks may occasionally misread timing or extensions. Verify in DevTools for the final word.
How the proxy works. A first-party proxy (like Google Tag Gateway via Cloudflare) routes Google's scripts through a path on your own domain (/m6yp/) so the tag manager loads without calling Google's domain directly.
Many modern ad blockers now look beyond the domain — they check for suspicious query strings (like G- measurement IDs) and response fingerprints. So the container may load through the proxy while the GA4 library further down the chain is still blocked. The container loaded by the snippet is GTM-P9R2TSK, separate from the other tests.
